Improve air circulation in your home

Welcome friends. Lets continue our discussion from where we left in our previous post. Please go through it to know more about the use case about the room having only a single door. Today, lets take another use case where we have one door and and a window.

This is one of the most familiar room structure in apartments and standalone houses. It has a door in one end and a window in the opposite side. First thing we need to check when both the door and window are open, does air circulate or flow from one side to another? It does matter because although you have passages for the same, the room may be surrounded by another closed wall particularly outside the door. For example, another room attached to the door side and what if the door and window of the same are closed. In that case, air will not be circulated. In most of the rooms as shown in the above picture, we do have ceiling fans. But in most of the cases, table fan as shown in the below picture has advantage as it can be placed according to your need and it can get you fresh air quickly.

In the above picture, the fan is blowing towards the window, creating low pressure instantly at its back and air will come from the door. In case of ceiling fan, air is blown downwards and that air tries to escape from both door and window. But from where the air will come in? The same door and the window have to do facilitate that. In the old houses, we always had ventilator just below the roof level. Now-a-days most of the builders do not provide that. Those ventilators played a vital role in facilitating incoming air for the ceiling fan which is at the similar level of that of the former. Another role of ventilator is to provide a passage to hot air to go outside. Remember, hot air has less density than cold air and the former stays above it.

Considering that we do not have ventilators in most of the rooms in our houses, table fan is more advantageous than ceiling fan! Follow the same practice in your home for couple of days and let me know the results.

Improve air circulation in your home

I have seen in many houses particularly in apartments, that the air inside a room or in the whole house does not circulate or it remains static. Most of us often neglect it or don't feel it. But at times, you will feel suffocated or you will wake up with dizziness or a heavy head. But you might have noticed that when you keep your exhaust on in the bathroom attached to your bedroom and sleep that night, the morning dizziness does not appear.

These all happen because of poor air circulation inside the house. The key is air should be able to come inside from outdoor and the air inside should be able to go out. If we take care of it, we can enjoy benefits of fresh air. Of course, air conditioning does the same thing besides controlling temperature and purifying air. But today we will discuss about achieving the same, in a much cheaper way.

Firstly, we have to see whether you have windows/doors at proper places in your house. Then based on that, we will figure out what best can be done for solving the problem. Lets take a use case.

This is a room having a single door, no other way air can travel in/out. What can we do now?

First of all, do not buy a flat having this kind of room, never. If at all you end up buying it, then you may have to do some wear and tear either with the wall or the door. For this kind of room, buy a door which is having holes in it. For example, door having net, grill door. Another kind of grill door known as ventilation door grill - which is very convenient for privacy, at the same time for air circulation as well. Once you fit this kind of door, that means you have just given a provision for air flow, but not actually enabled circulation. For that to happen, look at the figure below.

We have laid pipes along the roof or the side walls having an exhaust blowing inside. The fan will suck air into the pipe and exhales it far inside the room preferably the opposite corner of the room. Of course, there will be some amount of air which will flow from outlet into the inlet again. But due to suction near the door, air from outside the door (that is why ventilation door grill) will also flow in and keep the level of carbon dioxide low. You will definitely get fresh air.
